PARAMETER
Accuracy specifications tested at V
Rejection test. Tested for the ±10V input range.
External reference: V
Ground "on" channel; sine wave applied to all "off" channels.
Maximum full-power input frequency for 1LSB error with 10ns jitter = 3kHz.
Guaranteed by design. Not tested.
Use static loads only.
Tested using internal reference.
PSRR measured at full-scale.
External acquisition timing: starts at data valid at ACQMOD = low control byte; ends at rising edge of WR with ACQMOD
= high control byte.
